I have done so much reading on here and learned so much. But now I am in some trouble. I have 17 baby's 10 agent orange and 7 Sugar Babe. They are about 3 weeks old. I feed them nutes and I believe I burned them. They slowed to a crawl growing, the bottom leaves are yellow and have what looks like rust spots. Also they are drooping like they need water. I was planing on transplanting them and when I did (They were only in little cups) I noticed that the roots were a little brown. Would this be root rot? One of the nutes I use is brown, Is it just color from that? What ppm should I be around? The nutes I am using are A&B, Super B+, Prop-o-gator plant food for roots and humic acid. Is this a good combo? I am in a soiless mix. I have a box I build that is '4.5'x'4.5' I am running a 1000w air cooled hood (digital ballast) with a 530 cfm blower. I have 4 passive intakes. My temps are still a little high 80-82. The blower I bought was inexpensive. My humidly I am having trouble keeping over 30% Any help would be greatly appreciated. Again I have learned so much on here and love this site. Oh i have some pics....

How's your PH?

Only thing i dont know. I just ordered a ph meter should get here soon.

what should it be at? 5.5-6.5?

Yeah, between those. It sounds like what you're describing, that or MG deficiency but that can be caused by the PH if it's off.

what would i do? more water? what about the brown on the roots?

Chances are it's your ph being off and you're either going to have to continue watering with what you have until your meter comes or you will have to run to a store and by a ph kit. Any pet store would have one by the fish tanks.

thanks man i really appreciate the help

It turned out he had too much lime in the soil and he had to transplant to correct the problem.
